[0002] Silicon carbide reduction tank is a necessary reduction container for smelting sponge iron. Silicon carbide is used as the main material, which has excellent characteristics such as high temperature wear resistance, slag resistance, chemical corrosion to alkali, high thermal conductivity, oxidation resistance and thermal shock resistance. Silicon carbide reduction tank needs to be formed by ramming molding machine during production and processing.

An inverted motor is placed on the top surface of the ramming box, and a turntable connected to the motor output shaft is arranged above the ball head in the ramming box. An arc-shaped protrusion corresponding to the ball head is provided on the bottom surface of the turntable. The turntable is driven to rotate horizontally by the motor, and the protrusions at the bottom of the turntable push out the ramming hammer heads in turn in a circumferential direction to ram the silicon carbide powder. The ramming process is continuous without idle stroke, thereby improving the ramming efficiency of the silicon carbide reduction tank.

[0004] However, during use of the above device, when the ramming hammer rams the silicon carbide powder, the silicon carbide powder will be scattered due to the ramming of the ramming head. The scattered silicon carbide powder will flow in the workshop with the air, which will not only endanger the health of the workshop operators, but also lead to the waste of some silicon carbide powder.

[0024] A connecting assembly 4, used to connect the ramming rod 2 and the protective cover 301, a plurality of connecting assemblies 4 equidistantly distributed around the circumference are installed on the upper end of the protective cover 301;

[0025] The sponge ring 6 is used to block the gap between the ramming rod 2 and the protective cover 301 . The sponge ring 6 is movably sleeved on the outer side of the ramming rod 2 .

[0026] like Figure 1 , 5As shown, the base 1 is provided with a longitudinally extending support column, and a lifting frame is sleeved on the support column. The lifting frame is controlled to rise and fall by an electric push rod, and a ramming box is fixed on the lifting frame, and the ramming rod 2 is arranged in the ramming box; a ramming hammer head is provided at the bottom end of the ramming rod 2, and a ball head is provided at the top end of the ramming rod 2, and a spring is sleeved on the ramming rod between the ball head and the bottom surface of the ramming box, and an inverted motor is arranged on the top surface of the ramming box, and a turntable connected to the output shaft of the motor is arranged above the ball head in the ramming box, and an arc-shaped protrusion corresponding to the ball head is provided on the bottom surface of the turntable, and the turntable is driven to rotate horizontally by the motor, and the protrusions at the bottom of the turntable are pushed out in a circumferential direction in turn to ram the silicon carbide powder by each ramming rod 2. The above technology is the prior art and will not be elaborated on here.

[0027] See also Figure 1 A plurality of positioning rods 302 are fixedly installed on the outer side of the protective cover 301 , the positioning rods 302 can support the protective cover 301 , and one end of the plurality of positioning rods 302 away from the protective cover 301 is fixedly connected to the base 1 .

[0028] See also Figure 1 , Figure 2 An elastic gasket 303 is fixedly embedded at the lower end of the protective cover 301, and the lower end of the elastic gasket 303 is movably fitted with the upper end of the silicon carbide reduction tank molding mold. The elastic gasket 303 can enhance the sealing between the protective cover 301 and the mold. A movable tray 7 is installed at the upper end of the base 1 corresponding to the lower side of the protective cover 301. The movable tray 7 is used to hold the silicon carbide reduction tank molding mold, and the connection between the movable tray 7 and the base 1 is sliding contact.

[0029] The connecting assembly 4 includes a mounting base 401 fixedly connected to the protective cover 301 , and a movable striking rod 402 is mounted on one end of the mounting base 401 close to the ramming rod 2 , and the cross-section of the striking rod 402 is circular.

[0030] See also Figure 4 A hemispherical portion is provided at one end of the striking rod 402 close to the ramming rod 2. The hemispherical portion of the striking rod 402 is in active contact with the ramming rod 2 through a plurality of grooves 5. The hemispherical portion can reduce the friction between the striking rod 402 and the ramming rod 2.

[0031] See also Figure 4 One end of the striking rod 402 away from the ramming rod 2 is fixedly connected with a gasket 403, which can prevent the striking rod 402 from detaching from the mounting seat 401, and the side of the gasket 403 away from the striking rod 402 is movably abutted against a spring 404.

[0032] When multiple ramming rods 2 move down at one time to ram the silicon carbide powder, the multiple grooves 5 on the outside of the ramming rod 2 cooperate with the spring 404 to drive the ramming rod 402 to move back and forth. When the gasket 403 moves back and forth with the ramming rod 402, the gasket 403 repeatedly hits the mounting seat 401, causing the mounting seat 401 and the protective cover 301 to vibrate, which is conducive to vibrating the silicon carbide powder attached to the inner wall of the protective cover 301 and falling into the mold, avoiding accidental touching of the protective cover 301 during the subsequent unloading process, resulting in the powder attached to the inner wall of the protective cover 301 falling on the base 1 and making it inconvenient to clean.

[0033] The sponge rings 6 , which are equal in number to the ramming rods 2 , are fixedly bonded to the protective cover 301 .

[0034] When the ramming rod 2 moves up and down, the sponge ring 6 fills the gap between the ramming rod 2 and the protective cover 301 to prevent the silicon carbide powder from diffusing through the gap between the ramming rod 2 and the protective cover 301. The sponge ring 6 contacts the ramming rod 2 and can also clean the ramming rod 2.

[0035] When the molding machine is in use, the staff places the silicon carbide reduction tank molding mold on the movable tray 7, and then moves the mold to the lower side of the protective cover 301 through the movable tray 7; then the electric push rod lowers the lifting frame and the ramming box to a position where the elastic gasket 303 at the lower end of the protective cover 301 fits with the upper end of the silicon carbide reduction tank molding mold, and then starts the motor, which drives the turntable to rotate, and then drives the ramming rod 2 to ram the silicon carbide powder in the mold. During the ramming process, the protective cover 301 is covered above the mold by the positioning rod 302, which can prevent the silicon carbide powder from flowing and scattering in the workshop with the air, prevent the operator from inhaling the silicon carbide powder, and avoid the waste of silicon carbide powder.
